Abstract: As an alternative to synthetic chemicals, natural herbs can greatly improve fish's health and growth potential. This investigation aimed to explore the possibilities of oregano ( Oregano vulgare L.) extract as a phytogenic feed additive in improving the growth, blood profile, carcass composition, whole-body mineralization, serum biochemistry and antioxidant activity of Catla catla (average initial weight = 9.26±0.03 g/fish). Triplicate groups of fish were fed diets having various percentages of oregano extract (0 %, 0.5 %, 1 %, 1.5 %, 2 %, 2.5 % and 3 % per kg diet) twice daily for 90 days. The findings found that parameters of growth such as weight gain, weight gain%, feed conversion ratio, survival rate, protein efficiency ratio, and specific growth rate increased substantially ( p <0.05), in fish fed diets with 1 %-1.5 % oregano extract supplementation relative to the other treatments. Carcass composition and hematological parameters were improved significantly ( p <0.05) as oregano extract concentrations increased from 1 % to 1.5 % per kg compared to control and other groups. Results also indicated that minerals in the body of fish improved significantly ( p <0.05) when extract concentrations increased from 1 %--1.5 % in the diet. Furthermore, immune parameters and hepatic enzymes activities in fish improved considerably ( p <0.05) at these concentrations, indicating optimal antioxidant protection and disease resistance. In contrast, all fish parameters were decreased notably ( p <0.05) in control and groups based on 2.5 % and 3 % oregano extract. In conclusion, the supplementation of 1 %-1.5 % oregano extract in the diets of C. catla could significantly ( p <0.05) improve the overall performance of fish. • The medicinal herb, Oregano vulgare , offers a potentially cost-effective and sustainable alternative for fish feed. • Oregano extract enhances growth, health, and nutritional quality of Catla catla . • Adding 1 %-1.5 % oregano extract to C. catla fingerlings' diets boosts their immunity, growth, and overall health.
